Whatever your answer is, it will get you thinking on if and how to proceed into the commercial real estate world.All that being said, my general answer is YES, it is a good strategy.First step should be to start educating yourself about commercial real estate, how its valuation is based on profitability and not strictly on comps, how to leverage the power of partnerships to get large deals done through syndication, how job and population growth start playing a big role when evaluating markets to invest in, etc. 

@Valerie Copeland yes, perhaps that is a "wiser" decision for the reasons you listed but I do not think you should be deterred from analyzing and (possibly) putting offers on properties strictly due to the fact that either it was no tenant or has a bad tenant.

I am still learning the ropes, and I view this transaction as my training wheels into off market deals with strict criteria.

., there was a technical error, and the section of the tax code describing 15-year property (Section 168(e)(3)(E)) was in fact not amended to include qualified improvement property.So for now, strictly-speaking, in 2018, qualified improvement property is regular old 39-year property that is not eligible for bonus depreciation.We do expect that a technical correction to the law will be made, but for now the IRS has actually stated that it cannot guarantee that absent legislative correction it will accept the legislatively intended change in recovery period and bonus eligibility.Anyway, this is neither here nor there since you have stated you are a landlord of residential rental property rather than non-residential real estate.And this does not affect the application of 100% bonus depreciation to both qualifying new and used property place in service after 9/27/17 and before 1/1/23 that @Yonah Weiss pointed out.

As for the appraisal, if it's determined the home is worth only $22,500 you are still ahead of the ball game.DO NOT RELY STRICTLY on ZILLOW.    

I just bought a little studio on the beach I'm rehabbing and plan to rent it out as vacation rental and also am looking at buying another one in the same complex as a "strict rehab and sell".

I am pretty strict on our policies and its because if you allow one tenant to get away with certain things then their neighbori will also try the same thing. 

I purchased a vacation rental business called Tennessee Lakefront Cottages and focus strictly on leasing other people's lakefront homes for them.

But my real estate work is strictly a side hustle right now, since I work all day every day for USPS.

Not sure if this is strictly fair as the full rent would still be being paid under the terms of the lease by the other two tenants.I've gotten a lot of value from the insights on offer here on Bigger Pockets, and I'd appreciate any insight as to how you have handled similar issues in the past.
